With them installed, the car does not pass smoothly over the millions of speed bumps in cities, and even less so on roads in poor condition, the impacts are clearly transmitted to the whole body.
Are they good springs? Yes, without a doubt, but not for daily use or adverse weather conditions. They are only good for roads in good condition.

With ETKA and erWin you can find out the exact suspension references for the BlueGT.

Do a search for images of the BlueGT, GTI and WRC, to get a better idea of ​​what your 6C will look like later...
I have a full ETKA/ERWIN acces but because I don't have any BlueGT VIN I cannot found the right part number since there is many options available.

I checked on internet, and except BlueGT and WRC, GTI seems very high.
I mean her little ass :oops:

BTW, I think I'm gonna choose your setup.

EDIT:

I miss something, sorry

On this table:
runnin10.jpg
runnin10.jpg (79.49 KiB) Viewed 9396 times
And I quote you:

My R-line: (without sport chassis -15mm)

Front Axle from factory
L: 355mm
R: 355mm
Rear Axle from factory. Basic rear springs. 6Q0511115CD PR-1JP+0YE
L: 375mm
R: 375mm


355mm at the front match with the sport running gear on the table (351-+10mm)
So you have the sport chassis ? don't you ?

Or thanks to the table you are just in the limit of the standard running gear (366 +/-10mm) ?

On VW Workshop Manual for the 6C (not the 6R) here are the data:

And on ETKA, here are the options availables:

Nothing is matching G12/G70 spec for the "sport chassîs". And color coding for the spring are not available on internet.

When i did my rear suspension i just go with the PR:1JS code and built rear suspension from there. Original was with PR:1JP

6C0513025AJ is the sport suspension
6Q0511115CK is the sport spring for my polo r line weight

For the front suspension, I just got new stock front suspension with the powerflex top mount.

It's seems to be a total mess due to the variety of options/type of spring.... :? :shock:

Front axle spec:
-G72
-L39

So, for the front, I can't found any parts matching the weight of the car. Meaning, sport running gear was not available.
Only the sport select option was.

Rear axle spec:
-1JP
-0YN

So, for my rear axle I found a matching sport version:
-PR 1JS+0YN (weight spec): 6Q0 511 115 CL
and the dedicated coilover: 6C 513 025 AJ

So you keep the front suspension setup stock (not -15mm from the sport running gear ?).

Do you have any picture, just to get idea of how it will look like ?

The front is ok "stock" (could be -10mm) but the main issue is the rear.

Btw, I'm looking for the difference between the stock coilover and "sport" coilover.

Yes, my front axle is 'R-line' from the factory which means (at that time, 2012) that it is sporty and lowered by 15mm.
When I bought my 6R, VW offered the option '15mm lowered chassis' for the Sport models for X money (front and rear axle), I did not choose this option because being R-line the front axle already had it unlike the Sport models.
That is, by choosing the option, in my case I would have lost half of the option because being R-line I had it on the front axle.

My 6R felt good even with the stock rear suspension, but the aesthetics were horrible.🤭
By installing the BlueGT springs, without changing the shock absorbers, it felt just as good as with the stock springs but the aesthetics improved noticeably.😎

With the Eibach springs my R-line looked amazing, but the garage ramp and also the comfort made me remove them.

Thank you for the explanation !
Now it's way more clear 8)

So If I had to resume, your car, on R-Line, is already lowered from -15mm at the front but not at the rear FROM the factory.

That's why you ended up with the BlueGt rear spring to lowered that little ass.

Could you make me a favour ?
Since we have (almoste) the same front axle load limitation (870 kg vs 860kg), could you share me the part number of your front setup (coilover/spring) ?

Because on my ETKA, I cannot found any information for my weight code L39.
Or it's way too much, or way too low.

Thank you for your help !

3 white, 3 green.

:lol: ... impossible to take a picture of the shock absorber label without removing the wheel, in my setup everything is pretty tight there.
I had pictures of the labels, but they disappeared when the laptop's SSD died.🤦‍♂️

Oh thank you so much ! :D

Way better than nothing a least.
So according to the color code, part number is: 6R0411105B
PR:G10,G72,G73+L38

Maybe classic coilover could fit over those spring.
According to my VIN: 6C0413031CS
PR:G72+L39,L40,L41,L42,L54

or

Part number: 6C0413031CR
PR:G72+L53,L36,L37,L38

to match "Weight" L38 of the spring.

Funny thing is, 6Q0 511 115CL spring are not know on Autodoc or elsewhere.
Sachs is the OE to VW ?

To be honest, the difference is massive.

If you compare to mine:

z5hp.jpg (2.96 MiB) Viewed 9225 times
Everything was stock, 16" rims.

With your setup, the looks is perfect. Not too low, not too high.
And I presume comfort still okay.

6C0413031AH ?
That's what I found also :wink:

But becareful since they are now replaced with 6C0413031CR*

To be honest guys, thank you so much for your help ! :D

BTW, what is your axle load ?
Curious to see because of the different rear spring you will have compared to mine.

Concerning powerflex, why this kind of choose ?

BTW wich one ?

I don't remember seeing the manufacturer on the shocks on my 6R, maybe you might find it in images of second-hand parts, although I guess it depends on the place of manufacture...
Image

Image

Finding the combination of reasonable aesthetics and adequate comfort in the 6R/6C was always an odyssey. I think the OEM parts available for these quests are the best.
The R-line's front suspension is very good in these terms, it transmits a lot of security and in terms of comfort it is good enough to filter out the potholes.

For the manufacturer, for sure it will be Sachs for the coilover.
For the spring, I don't know but maybe also Sachs.

Btw, it's better to match "L" class weight of the coilover with the spring or the current state of the car ?

I mean, If I install, at the front "6R0411105B" (same as you), they are L38.
So for the coilover, it's better to choose:

-6C0413031CR (L38) to match the -15mm springs 6R0411105B
OR
-6C0413031CS (L39) like factory setup

The comfort feels the same if not better than before. I'm running all season tyres and my tyres pressure is one or two psi lower in the front and one or two psi higher in the rear than recommend. I find that is most comfortable for me.

My original stock rear shock and spring has PR-1JP+0YM and have upgrade it to PR-1JS+0YM.

I went with the -10mm Powerflex top mount bush.

Good news if the confort is the same or better. But like feeling, It's hard to describe and somebody can found a car comfortable and an other guy (for the same car) found the comfort pretty bad.

So you keep the same rear load axle code (0YM) and just swapp with sport version.

I never deal with powerflex, seems to be a well know company.
This mount seems to be harder or it's just a question of durabilIty ?

It was part of what I think will make some improvements to the front suspension while keeping the shock absorber and coil spring stock. I also replaced LCA with OEM rear solid bush and ARB bush with poly bush (Powerflex) at the same time, its did improved the handling and control, very noticeable for me. However it did add small increase in NVH between 1000-1800RPM.

Ive choose the purple version of Powerflex because they recommended for road use, the black version is much harder is for track use.
